Detailed Description

       A structure used to configure an Ethernet port. Depending upon the Rx multi-queue mode, extra advanced
       configuration settings may be needed.

Field Documentation

   uint32_t link_speeds
       bitmap of RTE_ETH_LINK_SPEED_XXX of speeds to be used. RTE_ETH_LINK_SPEED_FIXED disables link
       autonegotiation, and a unique speed shall be set. Otherwise, the bitmap defines the set of speeds to be
       advertised. If the special value RTE_ETH_LINK_SPEED_AUTONEG (0) is used, all speeds supported are
       advertised.

   struct rte_eth_rxmode rxmode
       Port Rx configuration.

       Definition at line 1519 of file rte_ethdev.h.

   struct rte_eth_txmode txmode
       Port Tx configuration.

       Definition at line 1520 of file rte_ethdev.h.

   uint32_t lpbk_mode
       Loopback operation mode. By default the value is 0, meaning the loopback mode is disabled. Read the
       datasheet of given Ethernet controller for details. The possible values of this field are defined in
       implementation of each driver.
